1. Analyze the bath solution daily,determine the concentrations of free sulfuric acid,stannous sulfate, nickel sulfate and total acid,replenish in time.

2. The additions scale of stannous sulfate to Sn&Ni Salt Electrolytic Coloring Additive is 1:1.1~1.2.

3. There will be white precipitations in long-time production, so the bath solution should be filtered and cleaned regularly.

is sealed with polybag, 5kg net each and 4 polybags in carton,20kg net each. Protected from light in a dry place.

Determination of stannous sulfate (SnSO4) content
Required reagents
①1% starch solution ② 0.1N iodine standard solution
Assay steps
Accurately draw 10mL of the test solution into a 250mL triangular beaker, add 100mL of water, add 5mL of 1:1 hydrochloric acid, and then add 5mL of 1% starch indicator, quickly titrate with 0.1N iodine standard solution, the solution turns from colorless to blue The color is the end point, and the volume V of the standard solution consumed is recorded.
calculate
Stannous sulfate (g/L)=10.73 × V × N

Determination of nickel sulfate (NiSO4) content
Required reagents
①30% hydrogen peroxide
②10% potassium sodium tartrate
③ 1:1 ammonia water
④1% purpuric acid amine
2. Assay steps
Take 1mL of coloring bath solution into a 250mL triangular conical flask, add 2mL (30%) hydrogen peroxide, heat to near dryness, add about 80mL water after cooling, 10mL (10%) potassium sodium tartrate, 20mL (1:1) ammonia water, A small amount of 1% ammonium purpurate was titrated with 0.01N EDTA standard solution until the solution turned purple as the end point.
calculate

Nickel sulfate (g/L)=262.9 × V × N Determination of total acid (H, SO)
1. Required reagents
0.1% Bromothymol Blue
② 1NNaOH standard solution 2. Assay steps
Accurately draw 10mL of the test solution into a 250mL triangular beaker, and add about 100mL of water. Add 4 drops of 0.1% bromothymol blue indicator, titrate with 1N NaOH standard solution, change from yellow to cyan as the end point, and record the volume V of NaOH consumed.
3. Calculate the total acid (
g/L)=4.9xVxN
Champagne coloring sink 2 — assay method

Determination of free acid (H2SO4)
Required reagents 1N NaOH standard solution
2. Assay steps
Accurately draw 50mL of the test solution into a 100mL beaker, titrate the pH to 2.1 with 1N NaOH standard solution under the measurement of the acidity meter, and record the consumed volume V.
calculate
Free acid ((g/L)=4.9 × V × N/5
